Description

Data transmission method, terminal equipment and network equipment

Technical Field

The present application relates to the field of communications, and in particular, to a method for transmitting data, a terminal device, and a network device.

Background

In LTE, a Media Access Control (MAC) Protocol Data Unit (PDU) mainly includes a MAC header (header), 0 or more MAC Service Data Units (SDU), 0 or more MAC control units (CE), and optionally some padding (padding).

Specifically, a MAC PDU header is composed of one or more MAC PDU subheaders (subheaders), each subheader corresponds to a payload (payload), and the payload may be a MAC SDU, a MAC CE, or a padding. In LTE, MAC CEs are typically placed before all MAC SDUs and after MAC subheaders. The MAC subheaders are connected together and placed in front of the MAC PDU, and correspond to the following MAC CEs, MAC SDUs and padding one by one.

Whereas in NR, the MAC PDU structure (format) will differ from the MAC PDU format in LTE in the following points:

firstly, the NR uplink MAC PDU and the downlink MAC PDU have different formats, and the formats of the LTE uplink and downlink MAC PDU are uniform;

secondly, the subheaders of the NR MAC PDUs are placed together with their corresponding payload, and the MAC subheaders are placed in front of the corresponding payload, instead of being placed in front of the MAC PDUs uniformly as in LTE;

thirdly, the MAC CE of the NR downlink MAC PDU and the corresponding MAC sub-header are arranged in front of the MAC PDU, and the design is mainly convenient for the UE side to quickly obtain the control information in the MAC CE;

fourthly, the MAC CE of the NR uplink MAC PDU and its corresponding MAC subheader are placed behind all MAC SDUs, and such design mainly considers that some real-time MAC CEs, such as Buffer Status Reports (BSRs), need to wait until the MAC SDUs are determined to be good before generating.

Since the uplink MAC CE in the NR system is located behind the MAC SDU in the MAC PDU, when the network device receives the MAC PDU sent by the end-point device, it needs to demodulate all the MAC SDUs before the corresponding MAC CE control information can be obtained, so that the network device cannot obtain the MAC control information of the terminal device as soon as possible.

Optionally, as an embodiment, the n MAC CEs and the corresponding n subheaders included in the first MAC PDU may be located between the m MAC SDUs and the corresponding m subheaders, padding, and the subheaders corresponding to padding. For example, fig. 2 shows a schematic diagram of a first MAC PDU according to an embodiment of the present application, that is, the arrangement order of each field in the first MAC PDU may be as shown in fig. 2.

Specifically, according to the position of the sub-header corresponding to the first MAC CE in the plurality of MAC CEs in fig. 2, that is, the position of the sub-header adjacent to MAC CE 1 and before the MAC CE, the first MAC PDU can be regarded as two parts, where the first part is m MAC SDUs and m sub-headers corresponding to the m MAC SDUs included in the first MAC PDU, that is, MAC SDU 1 and MAC SDU2, and the corresponding sub-headers, and the total number of bits of the first part corresponds to the first length shown in fig. 2; the second part is n MAC CEs, corresponding n subheaders, padding and subheaders corresponding to the padding, that is, MAC CE 1, MAC CE2, corresponding 2 subheaders, padding and subheaders corresponding to the padding, included in the first MAC PDU, and the total number of bits of the second part corresponds to the second length shown in fig. 2.

In this embodiment, the location information may include a number of bits between the specific bit and a first bit number of a subheader corresponding to a first MAC CE of the n MAC CEs. For example, as shown in fig. 2, the specific bit may be the first bit of the first MAC PDU, i.e., the first bit of the location information, and the location information may include the length of the location information and the first length. Correspondingly, the network device starts counting backwards from the first bit of the first MAC PDU according to the bit number in the location information, and may determine the first bit of the sub corresponding to the first MAC CE of the n MAC CEs included in the first MAC PDU, so as to obtain the n MAC CEs.

For another example, as shown in fig. 2, the specific bit may be a first bit of a subheader corresponding to a first MAC SDU of the first MAC PDU, and the location information may include the first length. Correspondingly, the network device starts counting backwards from the first bit of the subheader corresponding to the first MAC SDU of the first MAC PDU according to the bit number, i.e. the first length, in the location information, and may determine the first bit of the subheader corresponding to the first MAC CE of the n MAC CEs included in the first MAC PDU, thereby obtaining the n MAC CEs.

For another example, as shown in fig. 2, the specific bit may be the last bit of the first MAC PDU, i.e., the last bit of padding, and the position information may include the second length. Correspondingly, the network device may count from the last bit of the first MAC PDU to the front according to the bit number in the location information, that is, the second length, and may determine the first bit of the subheader corresponding to the first MAC CE of the n MAC CEs included in the first MAC PDU, so as to obtain the n MAC CEs.

For example, fig. 3 shows a schematic diagram of a first MAC PDU according to an embodiment of the present application, that is, the arrangement order of each field in the first MAC PDU may be as shown in fig. 3.

Specifically, according to the position of the sub-header corresponding to the first MAC CE in the multiple MAC CEs in fig. 3, that is, the position of the sub-header adjacent to the MAC CE 1 and located before the MAC CE, the first MAC PDU can be regarded as two parts, where the first part is m MAC SDUs and m corresponding sub-headers included in the first MAC PDU, and the sub-headers corresponding to padding and padding, that is, MAC SDU 1, MAC SDU2, 2 corresponding sub-headers, padding and the sub-header corresponding to padding, and the total number of bits of the first part corresponds to the first length shown in fig. 3; the second part is n MAC CEs and corresponding n subheaders included in the first MAC PDU, i.e. MAC CE 1, MAC CE2 and corresponding 2 subheaders, and the total number of bits of the second part corresponds to the second length shown in fig. 3.

In this embodiment, the location information may include a number of bits between the specific bit and a first bit number of a subheader corresponding to a first MAC CE of the n MAC CEs. For example, as shown in fig. 3, the specific bit may be the first bit of the first MAC PDU, i.e., the first bit of the location information, and the location information may include the length of the location information and the first length. Correspondingly, the network device starts counting backwards from the first bit of the first MAC PDU according to the bit number in the location information, and may determine the first bit of the sub corresponding to the first MAC CE of the n MAC CEs included in the first MAC PDU, so as to obtain the n MAC CEs.

For another example, as shown in fig. 3, the specific bit may be a first bit of a subheader corresponding to a first MAC SDU of the first MAC PDU, and the location information may include the first length. Correspondingly, the network device starts counting backwards from the first bit of the subheader corresponding to the first MAC SDU of the first MAC PDU according to the bit number, i.e. the first length, in the location information, and may determine the first bit of the subheader corresponding to the first MAC CE of the n MAC CEs included in the first MAC PDU, thereby obtaining the n MAC CEs.

For another example, as shown in fig. 3, the specific bit may be the last bit of the first MAC PDU, i.e., the last bit of the MAC CE2, and the location information may include the second length. Correspondingly, the network device may count from the last bit of the first MAC PDU to the front according to the bit number in the location information, that is, the second length, and may determine the first bit of the subheader corresponding to the first MAC CE of the n MAC CEs included in the first MAC PDU, so as to obtain the n MAC CEs.

For example, as shown in fig. 4, the specific bit may be a first bit of the first MAC PDU, that is, a first bit of a subheader corresponding to a first MAC SDU of the first MAC PDU, and the location information may include the first length. Correspondingly, the network device starts counting backwards from the first bit of the first MAC PDU, that is, the first bit of the subheader corresponding to the first MAC SDU, according to the bit number, that is, the first length, in the location information, and may determine the first bit of the subheader corresponding to the first MAC CE of the n MAC CEs included in the first MAC PDU, and further acquire the n MAC CEs.

For example, fig. 5 illustrates a schematic diagram of a first MAC PDU according to an embodiment of the present application, that is, the arrangement order of each field in the first MAC PDU may be as shown in fig. 5.

Specifically, according to the position of the sub-header corresponding to the first MAC CE in the MAC CEs in fig. 5, that is, the position of the sub-header adjacent to the MAC CE 1 and before the MAC CE, the first MAC PDU can be regarded as two parts, where the first part is m MAC SDUs and m corresponding sub-headers included in the first MAC PDU, and the sub-headers corresponding to padding and padding, that is, MAC SDU 1, MAC SDU2, 2 corresponding sub-headers, padding and the sub-headers corresponding to padding, and the total number of bits of the first part corresponds to the first length shown in fig. 5; the second part is n MAC CEs and corresponding n subheaders included in the first MAC PDU, i.e. MAC CE 1, MAC CE2 and corresponding 2 subheaders, and the total number of bits of the second part corresponds to the second length shown in fig. 5.

In this embodiment, the location information may include a number of bits between the specific bit and a first bit number of a subheader corresponding to a first MAC CE of the n MAC CEs. For example, as shown in fig. 5, the specific bit may be a first bit of the first MAC PDU, that is, a first bit of a subheader corresponding to a first MAC SDU of the first MAC PDU, and the location information may include the first length. Correspondingly, the network device starts counting backwards from the first bit of the first MAC PDU, that is, the first bit of the subheader corresponding to the first MAC SDU, according to the bit number, that is, the first length, in the location information, and may determine the first bit of the subheader corresponding to the first MAC CE of the n MAC CEs included in the first MAC PDU, and further acquire the n MAC CEs.

For another example, as shown in fig. 5, the specific bit may be the last bit of the position information, and the position information may include the length of the position information and the second length. Correspondingly, the network device may count from the last bit of the first MAC PDU to the front according to the number of bits in the location information, and may determine the first bit of the sub corresponding to the first MAC CE of the n MAC CEs included in the first MAC PDU, so as to obtain the n MAC CEs.

For another example, as shown in fig. 5, the specific bit may be the last bit of the MAC CE2 of the first MAC PDU, and the location information may include the second length. Correspondingly, the network device may count from the last bit of the MAC CE2 in the first MAC PDU to the front according to the number of bits in the location information, that is, the second length, and may determine the first bit of the sub corresponding to the first MAC CE of the n MAC CEs included in the first MAC PDU, so as to obtain the n MAC CEs.

Optionally, as an embodiment, the position information may also be located in a subheader corresponding to the padding, for example, bits in the subheader corresponding to the padding may be multiplexed. Specifically, when n MAC CEs and n corresponding subheaders included in the first MAC PDU are located between m MAC SDUs and m corresponding subheaders, a padding and subheaders corresponding to the padding, that is, fig. 6 shows a schematic diagram of the first MAC PDU according to the embodiment of the present application, that is, an arrangement sequence of each field in the first MAC PDU may be as shown in fig. 6, where the padding is located before the corresponding subheader and the subheader corresponding to the padding includes location information.

Specifically, the subheader corresponding to the padding may be used to indicate the length of the padding, and when the subheader includes a position information pair, the position information may include a bit number between a specific bit and a first bit number of the subheader corresponding to a first MAC CE of the n MAC CEs, and then the subheader corresponding to the padding may be used to indicate a bit number from the first bit of the subheader corresponding to the first MAC CE to a last bit of the padding. The network device may count forward from the last bit of the padding according to the number of bits included in the subheader corresponding to the padding, may determine the first bit of the subheader corresponding to the first MAC CE of the n MAC CEs included in the first MAC PDU, and further obtain the n MAC CEs.

It should be understood that the location information in the embodiment of the present application may be an independent field, that is, for example, as shown in fig. 2 to 5, may be located at the foremost or rearmost part of the first MAC PDU, and may have a size of at least 1byte (byte), for example, as shown in fig. 7, the location information may be 1byte, that is, 8 bits (bit), or the location information may also be 2 bytes, and the embodiment of the present application is not limited thereto.

Optionally, the location information may also multiplex a certain field in a subheader corresponding to padding in the first MAC PDU, for example, as shown in fig. 6, the subheader corresponding to padding includes the location information, the location information may multiplex an L field indicating a length (length) in the subheader, and then the size of the location information is equal to the size of the L field.

Specifically, fig. 8 shows a schematic diagram of a subheader corresponding to padding according to an embodiment of the present application, and as shown in fig. 8, the subheader may include an R field, where the R field is a reserved bit (reserve bit); the subheader further includes an F field, where the F field is used to indicate the size of an L field included in the subheader, for example, as shown in fig. 8, the size of the L field may be 8 bits, and then the F field indicates that the size of the L field is 8 bits; the subheader further includes a Logical Channel Identity (LCID) field, where the LCID is used to indicate that the subheader is a subheader corresponding to the paging; the subheader further includes an L field for carrying location information, for example, as shown in fig. 8, the size of the L field may be 1byte, but the embodiment of the present invention is not limited thereto.

Optionally, the method 100 may further include: and the terminal equipment determines effective indication information, wherein the effective indication information is used for indicating whether the network equipment needs to determine the positions of the n MAC CEs included in the first MAC PDU according to the position information.

For example, when the total length of the first MAC PDU is greater than or equal to a first preset value, or the total length of m MAC SDUs included in the first MAC PDU is greater than or equal to a second preset value, the terminal device may set the validation indication information to indicate that the network device needs to determine the positions of n MAC CEs included in the first MAC PDU according to the location information, for example, the validation indication information may be set to one bit, and "1" indicates that the network device needs to determine the positions of n MAC CEs included in the first MAC PDU according to the location information, and then the network device may determine whether to determine the positions of n MAC CEs included in the first MAC PDU according to the validation indication information.

In addition, since the total length of the first MAC PDU is larger or the total length of the m MAC SDUs included in the first MAC PDU is larger at this time, the position information may be set to search the positions of the n MAC CEs from the following bits of the first MAC PDU, but the embodiment of the present application is not limited thereto.

Correspondingly, when the total length of the first MAC PDU is less than the first preset value pair, or the total length of m MAC SDUs included in the first MAC PDU is less than the second preset value, the terminal device may set the validation indication information to indicate that the network device does not need to determine the positions of the n MAC CEs included in the first MAC PDU according to the location information, for example, the validation indication information may be set to one bit, and "0" indicates that the network device does not need to determine the positions of the n MAC CEs included in the first MAC PDU according to the location information, and then the network device may determine whether to determine the positions of the n MAC CEs included in the first MAC PDU according to the validation indication information.

It should be understood that the first preset value and the second preset value may be set according to actual situations, and the embodiment of the present application is not limited thereto.

For another example, for a special case where other network devices need to determine the location of the MAC CE, the terminal device may also set the validation indication information to indicate that the network device needs to determine the locations of the n MAC CEs included in the first MAC PDU according to the location information, but the embodiment of the present application is not limited thereto.

It should be understood that the location information and the validation indication information in the first MAC PDU may be set as consecutive fields, which together occupy at least 1byte, for example, may occupy 1byte or 2 bytes. Specifically, as shown in fig. 9, the position information and the validation indication information together have 1byte, where the validation indication information occupies 1 bit (bit), and for example, the bit may be set to "1" or "0"; and the position information occupies the remaining bits, i.e., 7 bits.

Optionally, for a case that the subheader corresponding to the padding includes the location information, the subheader may also include the validation indication information, that is, the validation indication information and the location information jointly multiplex an L field in the subheader corresponding to the padding.

Optionally, as an embodiment, the method 100 may further include: the terminal device may also transmit a second MAC PDU to the network device, where the second MAC PDU may include indication information indicating that the MAC CE is not included in the second MAC PDU.

Specifically, when the MAC PDU includes the MAC CE, the terminal device may indicate, through the location information and the validation indication information, that the network device includes the MAC CE in the MAC PDU and indicate the location of the MAC CE, that is, the first MAC PDU sent to the network device by the terminal device may include the location information, where the location information is used to indicate the locations of the n MAC CEs included in the first MAC PDU. When the MAC PDU does not include the MAC CE, the terminal device may indicate, through the indication information, that the network device does not include the MAC CE in the MAC PDU.

It should be understood that the indication information included in the second MAC PDU is similar to the location information included in the first MAC PDU, for example, the location and size of the indication information may be consistent with the location information, i.e., when the MAC CE is included in the MAC PDU, the location information is included in the MAC PDU; when the MAC PDU does not include the MAC CE, the MAC PDU includes the indication information, that is, the indication information can be regarded as the case where the location information is a special value, which is not described herein again.

For example, as shown in fig. 7, the indication information may be 1byte, and a special value indicated by the 1byte indicates that the MAC PDU does not include a MAC CE, but the embodiment of the present invention is not limited thereto.
